From the customer's point of view, since the electronic document is provided, the sample is also provided, and the last printed result has also proved that the electronic document can print the provided sample color. The consistency of different printing colors is very important, why? Can the printing company not print the printed color the same as the last sample color? Causes of difficulty in chasing color What is the root cause of this problem? As far as the author company is concerned, the quality of equipment and materials is not good enough, nor is it the technical experience of the printing workers. However, if you want the same electronic documents and the results of different printings to be consistent, you need to pass the basic color detection every time you print. The chromaticity value, the chromaticity value of the overprinted color, the dot gain value and the like reflect the characteristic parameters of the printing process, and adjust the CTP output curve, the amount of printing ink or the printing color sequence, so that different printings have an approximate reflection of the printing process. Characteristic parameters, this is the requirement of printing standardization. Difficulties in printing standardization Printing companies all know the importance of standardization and dataization in the printing production process. There are few companies that can really do it. The main reason lies in the standardized testing of printing production, especially the detection of color parameters. The operation is too complicated for the printing workers. Technical requirements exceed the level of competence of the average printer. Only by combining the existing methods with the actual production of the enterprise, using the technology that is easy to use, operability and acceptable to the printing workers, the printing standardization can be implemented in production and then transformed into productivity. Based on this consideration, the author's company and Hangzhou University of Electronic Science and Technology have jointly developed a set of printing quality analysis tools, including printing quality analysis and control software, scanning measuring devices and corresponding digital control strips, which are required for printing standardization. Measurement, analysis and control become easy to use, and printing standardization is no longer at the concept, but can be implemented in the production process. Application of printing quality analysis tools 1. Fast scan detection The printing quality analysis tool we developed is measured in a scanning manner, and it can complete one measurement of the measuring strip of the opposite web and about 100 color patches in 10 to 20 seconds, which not only completes the information more complete. And the measurement efficiency can be greatly improved. 2. Determine the optimal amount of ink The printing quality analysis tool can not only obtain the ink quantity data of each ink area according to the scanning detection result, automatically calculate the chromaticity value and density of each ink area, and obtain the minimum color difference between the current ink area and the standard requirement (and can be based on The current relationship between the chromaticity value and the density of each ink zone, the optimal density is derived, and set to the standard density. The printer can not only easily obtain the best density value, but also see other inks based on the optimal density. The density distribution of the regions facilitates the increase and decrease of the amount of ink in the other ink regions, so that the density of each ink region is brought closer to the optimum density. 3. Automatic analysis and evaluation of printing quality Under the condition that the ink quantity meets the standard requirements, the printing quality analysis tool can easily obtain the density of the basic color, the overprinting rate of the overprinted color, the color difference information, the relative contrast information, the realization of the gray balance, the color gamut comparison, and the dot enlargement to reflect the printing process. The characteristic parameters are scored according to the deviation of each indicator from the standard requirements, and the total score is obtained, which further reduces the technical requirements for analyzing and evaluating the printing quality. After completing the printing quality analysis and evaluation, you should first pay attention to the total score and have an understanding of the overall quality of the printing. If the total score is not high, then look at each individual score to find out which single item has a low quality score, and then take corresponding measures to adjust the process. Compared with the traditional single point detection, recording, calculation and analysis, this method can greatly improve the efficiency, and is simple and clear, and has low technical requirements for the printing workers. Managers or customers can also monitor and evaluate print quality based on ratings, while technically savvy professionals can further optimize process conditions based on specific parameters. 2-10 Makeup Brush sets are used.

1. The big brush
It can be used as a base for large areas of eye shadow, and can also be used as a splash foundation.
2. Foundation Brush
The role of the foundation brush is to apply liquid foundation and foundation cream to evenly make up the face;
The foundation brush can be selected according to the following points: the density of the bristles should be tight and the quality of the bristles is harder; the bristles should be oblique trapezoid, and the brushes with good elasticity of the bristles should be selected; it is best to choose mink or synthetic fibers in terms of material.

How to use the nose bridge brush
4. Fan Brush
The main function of the fan brush is to sweep away excess loose powder and eye shadow powder on the face.
5. Eye shadow brush
Eye shadow brushes can show soft colors, and can be subdivided into many different styles according to their functions. If you don't know how to choose, it is recommended to buy a large, medium and small eyeshadow brush first;
A large brush is used to apply light-colored eyeshadow as a primer; a medium-sized brush can be used to retouch the eye area more delicately; a small-sized brush is used to refine the eyeshadow, especially one with a tight, angled brush head, which can be used to strengthen the eyes Outline.
6. Concealer Brush
Concealer brushes, as the name suggests, are used to apply concealer products to the areas that need to be concealed, such as spots, acne marks, dark circles, etc. It can help you to create the details. Usually used in conjunction with a foundation brush, using a concealer brush can make the concealer more even and natural.
7. Lip Brush
Lip brush, lip balm and lip gloss, can also be used to brush eyeliner, when applying lipstick, start from the lower lip. In the drawn lip line, apply from the inside out. When applying lip gloss with a lip brush, do not use too much force, and do not bend the bristles too much, so as not to fall off and break.
